Enable Apple TV Subtitles
While a video is playing, hold down the Select (center) button on your Apple TV remote to bring up the Options menu, then choose the Subtitles view. If there are embedded or external subtitles associated with the video they will appear in the list. If you are using Silver Screen to AirPlay video to the Apple TV, it will dynamically extract the subtitles and send them to the Apple TV.
